A new exhibition exploring how fashion survived and even flourished during World War II has opened at the Imperial War Museum in Lambeth to mark the 70th anniversary of the war’s end. Fashion on the Ration brings together more than 300 exhibits including clothes and accessories like the ‘respirator carrier handbag’, photographs and films as well as official documents from the period, letters and interviews. The exhibition is divided into six parts which examine in detail everything from the uniforms worn during the period to clothes rationing (introduced in 1941) and how the end of the war impacted fashion. Runs until 31st August. Admission charge applies. For more, see www.iwm.org.uk.

The UK’s first major exhibition devoted to Paul Durand-Ruel, the man who “invented Impressionism”, has opened at the National Gallery off Trafalgar Square this week. Inventing Impressionism features around 85 works including some of Impressionism’s greatest masterpieces, a number of which have never been seen in the UK before. The majority of the works were traded by Durand-Ruel (1831-1922) who is noted for having discovered and supported Impressionist painters like Monet, Pisarro, Degas and Renoir. Durand-Ruel purchased an astonishing 12,000 pictures between 1891 and 1922, including more than 1,000 Monets, about 1,500 Renoirs, more than 400 Degas’, some 800 Pissarros and close to 200 Manets. The images on display include a series of rarely-seen portraits of the dealer and his family by Renoir which are being exhibited in the UK for the first time as well as five paintings from Manet’s ‘Poplars’ series and all three of Renoir’s famous ‘Dances’, not seen in the country together since 1985. The exhibition finishes with a reference to an exhibition Durand-Ruel organised in London in 1905. Held at the Grafton Galleries, it presented 315 paintings. Admission charge applies. Runs until 31st May. For more, see www.nationalgallery.org.uk.

Gift Horse, New York-based German artist Hans Haacke’s sculpture of a skeletal riderless horse, will be unveiled on the Fourth Plinth in Trafalgar Square today. The horse, derived from an etching by English painter George Stubbs – whose works are in the nearby National Gallery, features an electronic ribbon tied to the horse’s front leg showing a live ticker of the London Stock Exchange. The statue, described as a ‘wry comment’ on the equestrian statue of King William IV which was originally to occupy the plinth, is the 10th to occupy the plinth since the first commission – Marc Quinn’s sculpture Alison Lapper Pregnant – was unveiled in 2005.

 Contemporary artist Dryden Goodwin’s first feature-length film is on show as part of a new exhibition, Unseen: The Lives of Looking, at the Queen’s House in Greenwich. Continuing Goodwin’s investigations into portraiture, the newly commissioned film focuses on three individuals who have a “compelling” relationship to looking – eye surgeon Sir Peng Tee Khaw, planetary explorer Professor Sanjeev Gupta and human rights lawyer Rosa Curling. Alongside the screening is a series of drawings made by Goodwin after observing the three individuals as well as tools and papers related to each of their trades and a series of objects connected three leading observers related to the history of the Royal Museums Greenwich sites – John Flamsteed, first Astronomer Royal, Edward Maunder, who observed Mars from the Royal Observatory Greenwich, and the artist Willem van de Velde the Elder who made detailed drawings of naval battles in preparation for producing paintings in his studio at the Queen’s House. Runs until 26th July. Admission is free. For more, see www.rmg.co.uk.

• It’s all about the Olympics in London this week and many of the events – like the Opening Ceremony and Torch Relay (see last week’s post) – are well covered elsewhere, but we thought we’d mention a couple of things in relation to the Games: 

The first is the ‘All the Bells’ project which will see bells across London being rung at 8:12am on Friday to “ring in” the first day of the Olympic and Paralympic Games. Work No. 1197: All the bells in a country rung as quickly and as loudly as possible for three minutes, commissioned as part of the London 2012 Festival, is the brainchild of Turner Prize-winning artist and musician Martin Creed and will involve thousands of bells across the nation. Speaking of bells, the City of London has announced that some of the City’s churches will be ringing continuously during the three Olympic marathon events – the men’s, women’s, and Paralympic events. As many as 57 of the country’s most experienced bell ringers, co-ordinated by the Ancient Society of College Youths (a ringing society created in London in 1637) will be working for three to four hours continuously at churches including St Paul’s Cathedral, St Mary le Bow, St Lawrence Jewry, St Magnus the Martyr, St Vedast and St Katharine Cree. During the women’s marathon, an all-female band will be attempting a peal at St Paul’s, the first all-woman attempt on the bells. (Apologies, this article had originally had the time for the bell ringing at 8.12pm – it is in the morning, not the evening!)

A new exhibition exploring London’s Olympic history has opened at the British Library. Olympex 2012: Collecting the Olympic Games features a range of memorabilia including a swimming costume and the finishing tape broken by – later disqualified – marathon runner Dorando Pietri  from the 1908 London Games (see our earlier post for more on him) as well as posters and artworks, stamps, letters and postcards. The exhibition also features audio interviews with Olympians including William (Bill) Roberts, a relay runner in the 1936 Berlin Olympics, and Dorothy Tyler, a medal-winning high jumper who competed in the 1936 and 1948 Olympics. Presented by the British Library and International Olympic Committee, the exhibition runs until 9th September at the library in St Pancras. Entry is free. For more, see www.bl.uk.

• A new free wifi network has been launched in London’s West End. Westminster City Council and telco O2 launched the network this week. It will initially cover Oxford and Regent Streets, Trafalgar Square, Leicester Square, Piccadilly Circus and Parliament Square with further areas in Westminster and Covent Garden the next to be included in the network. A once-only registration process is required to join.

• Henry Moore’s famous sculpture, The Arch, has been returned to its original home in Kensington Gardens. The six metre high work was presented to the nation by Moore in 1980 and was positioned on the north bank of the Long Water until 1996 when the structure became unstable and was placed in storage. In late 2010, the Royal Parks began a project with The Henry Moore Foundation to see if the work could be returned to the gardens. Work began to restore the piece – which consists of seven stones weighing 37 tonnes – to its original location earlier this year. For more on Kensington Gardens, see www.royalparks.org.uk/parks/kensington-gardens.

• On Now: From Paris: A Taste for Impressionism. This Royal Academy of Arts exhibition at Burlington House features 70 works from the Sterling and Francine Clark Art Institute in Williamstown, Massachusetts, and includes works by Manet, Monet, Pissarro, Degas, Sisley, Morisot and Renoir as well as those of post-Impressionist artists Corot, Théodore Rousseau and J-F. Millet, and ‘academic’ paintings by Gérôme, Alma-Tadema and Bouguereau. Runs until 23rd September. Admission charge applies. See www.royalacademy.org.uk for more.
